After installing a cloned site, cannot update "Date Published" field on any posts | Wordpress Support | Forum Archive

I successfully cloned a WordPress site from one hosting environment and then copied it over to another hosting environment (by unpacking the files and the database) using XCloner.

In the cloned version, everything appears to be as it should be, and I did not see any problems with plugins, user accounts, anything.

Except that all the posts that were copied over now say in the "published on" field (which is a set of date/time fields): 

"Copy from original" 

And the month is editable (it's a dropdown list) but none of the other date/time fields are editable. The fields now have a grey background instead of the normal white background.

Thoughts? Is there an edit I can do to the table data to clear this up?
